Abstract

The utility model discloses a mechanical limiting device of the hydraulic cushion of a small- and medium- scale hydraulic press, which comprises a hydraulic press lower cross beam, wherein, the hydraulic cushion is arranged in the lower cross beam; a screw hole is formed on one side of the hydraulic cushion; a long oblong hole is formed in the position of the lower cross beam corresponding to the screw hole; a screw bolt is inserted into the screw hole to allow one end of the screw bolt protrude the outer side of the lower cross beam through the long oblong hole; a limit rod is mounted on the screw bolt; a big and a small link stoppers are mounted on the limit rod; and an upper proximity limit switch, an upper limit switch and a lower limit switch are mounted on the side of the long oblong hole of the lower cross beam. When the device is stopped, the hydraulic cushion falls in the lowest position; the big link stopper is in contact with the limit switch of the lower limit; when in operation, a hydraulic cushion cylinder drives the hydraulic cushion to move upwards; the limit rod is driven to move upwards in the long oblong hole along with the hydraulic cushion until the small link stopper is in contact with the upper limit switch; and the superior limit switch serves the function of safe-keeping. The limiting device has the advantages of simple structure and convenient operation when is applied in the stroke limiting of the hydraulic cushion of a small- and medium- scale hydraulic press.

Description

The hydraulic die cushion mechanical stop limiter of middle-size and small-size hydraulic press
Technical field:
The utility model relates to mechanical stop limiter, the hydraulic die cushion mechanical stop limiter of more specifically saying so and being applied in middle-size and small-size hydraulic press.
Background technology:
At present known in large hydraulic press, hydraulic die cushion adopts displacement sensor device, exists precision too high but be applied in the hydraulic die cushion of middle-size and small-size hydraulic press, improves the situation of production cost.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, be provided at the hydraulic die cushion mechanical stop limiter of middle-size and small-size hydraulic press, and touching by collision block and mechanical limit switch provides limit signal, guarantees that hydraulic die cushion moves in prescribed stroke.
The technical scheme that the utility model technical solution problem is adopted is:
The hydraulic die cushion mechanical stop limiter of middle-size and small-size hydraulic press, include the hydraulic press sill, the hydraulic die cushion cylinder is installed in the sill, described hydraulic die cushion cylinder piston end is fixedly connected with hydraulic die cushion, it is characterized in that on the described hydraulic die cushion sidewall screw rod being installed, described screw rod stretches out from the long lumbar hole on the sill on its next door, screw rod can move up and down and satisfy the stroke of hydraulic die cushion in described long lumbar hole with hydraulic die cushion, the screw rod end is fixedly connected with gag lever post, described long lumbar hole next door is equipped with limes superiors from top to bottom successively, upper limit, the lower limit mechanical limit switch, described gag lever post lower end also is equipped with big, little two collision blocks.
The device of the hydraulic die cushion mechanical position limitation of described middle-size and small-size hydraulic press, it is characterized in that hydraulic die cushion is contained in the sill, screw about a side setting of hydraulic die cushion, the position corresponding with sill at the hydraulic die cushion screw has long lumbar hole, and the length of long lumbar hole will guarantee that hydraulic pressure is lined with enough strokes.
The device of the hydraulic die cushion mechanical position limitation of described middle-size and small-size hydraulic press, it is characterized in that at described screw rod be two, be installed in two screws on the hydraulic die cushion sidewall, screw rod the outer end gag lever post is installed, the gag lever post lower end is by screw thread and adorn large and small two collision blocks.
The device of the hydraulic die cushion mechanical position limitation of described middle-size and small-size hydraulic press is characterized in that the distance between the upper and lower spacing mechanical limit switch is exactly the range of hydraulic die cushion, and little collision block can be adjusted arbitrarily in maximum travel limit in the position on the gag lever post.
Hydraulic die cushion is upwards operation under the promotion of hydraulic die cushion cylinder, drives gag lever post also along with hydraulic die cushion upwards operation in long lumbar hole, contacts with the upper limit mechanical limit switch up to little collision block to stop.
Make hydraulic die cushion drop on upper/lower positions when stopping, big collision block contact with the lower limit mechanical limit switch, and collision block is adjusted and then fixed with nut greatly, does not allow any change.
The limes superiors mechanical limit switch has been the safeguard protection effect.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model adopts mechanical stop limiter, is used in the hydraulic die cushion stroke limit of middle-size and small-size hydraulic press, and this is simple in structure, and is easy to process, and operation had both guaranteed product quality easily, fell end production cost again.
Description of drawings:
